There is huge contention on inserting into RHQ resource error table - looks like from the (only 700 rows) like those may come from multiple plugins sending reports about ResourceComponent unable to start at around the same time (as with the perf plugin)
Statement is
insert into RHQ_RESOURCE_ERROR (TIME_OCCURRED, RESOURCE_ID, ERROR_TYPE, SUMMARY, DETAIL, ID) values (:1 , :2 , :3 , :4 , :5 , :6 )
